....But Wisdom in particular was always an issue even back in the day, when the question would be "what is the real functional and fundamental difference between Intelligence and Wisdom?"....
The distinction between intelligence and wisdom is very real and appropriately represented in AD&D.
Religion is the means by which a culture stores its accumulated wisdom, not empirically, but through mythical story-telling.
When people practice the religion of their culture, they are embodying their ancestors' ancient knowledge without necessarily understanding it empirically. This is represented in AD&D by the fact that magic-users must learn their spells, whereas clerics are simply given their spells.
High wisdom provides some resistance to mental attack forms involving will force. This makes sense because people who practice religion are more resistant to despair, anxiety, and other attacks against the mind. That is because our ancestors learned long ago how to withstand these mental assaults, otherwise we would not be here.
Naturally, people who are irreligious do not understand wisdom, and the more empirically minded they are, the more this is true.
Our culture has had what is in essence a spiritual stroke because it has become too empirical. The problem is that the world is too complex for the human brain to understand in strictly empirical terms. Holistic apprehension is more complete but less specific -- a picture is worth a 1,000 words.
People have latched onto the corona virus hysteria largely because it's something that they can understand in empirical terms; everyone knows what a virus is and how it works. The corona virus is a stand-in for aspects of reality that trouble our culture, but which most can no longer understand, in the same way that demons were once stand-ins for diseases which people did not understand.
The two hemispheres of the brain are hard-wired differently:
Left hemisphere: Operation in Explored Territory
positive affect
activation of behavior
word processing
linear thinking
detail recognition
detail generation
fine motor action
Right hemisphere: Operation in Unexplored Territory
negative affect
inhibition of behavior
image processing
holistic thinking
pattern recognition
pattern generation
gross motor action
There is an obvious correlation between the hemispheres and intelligence/wisdom.
